Roller coating machine

Abstract

The invention relates to a roller coating machine. Workpieces needing to be coated are pushed into a material turnover frame of a material turnover mechanism; the material turnover mechanism rotates the material turnover frame; the workpieces are turned and are poured into a material blocking hopper; the workpieces are conveyed to a material storage hopper of a discharge mechanism by a discharge conveying machine; the workpieces are lifted by the discharge mechanism, then are arranged in order and roll into a vibration transmission rack according to a certain rule; the workpieces are conveyed to a synchronous material-pushing mechanism; the workpieces arranged tidily are pushed to a V-shaped groove of a synchronous material-loading mechanism by the synchronous material-pushing mechanism; the workpieces are subjected to position adjustment by the synchronous material-loading mechanism and then are pushed to a material hanging mechanism on a workpiece transmission rack; the material hanging mechanism drives the workpieces and feeds them into an automatic glue-rolling device; a glue liquid is uniformly roll-coated on the surfaces of the workpieces by the automatic glue-rolling device; the workpieces coated with the glue liquid are fed to an unloading mechanism by the workpiece transmission rack; and the workpieces coated with the glue liquid are fed to a material receiving hopper by the unloading mechanism, then are fed into a workpiece delivery wagon and then are output. The roller coating machine adopts a roll-coating technology to realize workpiece surface treatment, is efficient, saves energy, is environmentally friendly and is suitable for large-scale glue-rolling of tubular workpieces.

Description

technical field [0001] The invention relates to an automatic roller coating device for treating the outer surface of a tubular workpiece, in particular to a roller coating machine for surface treatment of a workpiece by using the roller coating technology, which belongs to the technical field of mechanical manufacturing. Background technique [0002] In the prior art, glue spraying and painting processes are mostly used for the outer surface treatment of tubular workpieces. This treatment process mainly has the following disadvantages: (1) Spraying will cause the working environment to be filled with mist-like harmful gases, which will harm human health; (2) The utilization rate of raw materials in the spraying method is low, and the nozzles are prone to clogging. Unevenness, poor spray adhesion, and product quality cannot be effectively guaranteed. [0003] In view of the shortcomings of the traditional spraying process, the applicant designed an automatic roller coating e...
